Engine issues, all stemming from the turbos on my old 5-series. Anytime I'd have to go up a hill or accelerate period, I'd get this warning saying I need to get to a dealership since my engine isn't getting all the power needed. And idk if anyone else had this issue with theirs but the two 5s I had both had water leakage in them. Something about the vapor barrier. Got them shyts switched out and would still flood. Then was told it was something with the moon roof. I Usain Bolted down to the local GMC dealer and traded that hoe in. Soon as I pulled into the lot, fukkin lights went out. Got $10k for it tho. And I was the dude who always went before the suggested maintenance date/mileage to get my shyt serviced. Will NEVER step foot in one again. The issues not worth it. Lights alone cost $5k. Turbo issue ran $8k and that's after I fixed another engine issue that ran me $4k
